<h3>What is an expression?</h3>

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2.3 raised to the fifth power divided by 0.9 raised to the fourth power, all raised to the third power.

Write the expression in the mathematical form and solve:-

[ ( 2.9⁵) / ( 0.9 )⁴ ]³ = [ ( 2.9⁵) / ( 0.9 )⁴ ]³

                             =  [ ( 2.9 )¹⁵ / 0.9 )¹² ]

Therefore, the given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.

What are the domain and range of the function f(x) = 3x + 5? domain: (negative infinity, infinity); range: (0, infinity) domain:
AlekseyPX

Answer:

Domain : (-∞,∞)  Range : (-∞,∞)

Step-by-step explanation:

Given:

f(x) = 3x+5

To find: Domain and Range of f(x)

Domain is the set of values that x can take.

Range is the set of values of y corresponding to the values of x in the domain.

Here x can take any value and the domain is the set of real numbers i.e (-∞,∞).

f(x) = 3x + 5

The graph of f(x) is a straight line that extends from -∞ to +∞ and hence the range is (-∞,∞).
